Coin: “What is a Coin? Coin is a connected device that can hold and behave like the cards you already carry. Coin works with your debit cards, credit cards, gift cards, loyalty cards and membership cards. Instead of carrying several cards you carry one Coin. Multiple accounts and information all in one place. – How do I get my cards onto a Coin? Our mobile app will allow you to add, manage and sync the cards that you choose to store on your Coin. The process of adding card information to the mobile app is very simple and is done by taking a picture or two and swiping your Coin through a small device we provide you with. – How much does a Coin cost? Each Coin costs $100. For you early adopters there is a very limited quantity that can be purchased for $50.”

TC: “We are, I believe, in an interstitial zone when it comes to payments. Credit cards are still king – just ask Square – and NFC is just a dream in most countries. That’s why Coin is so interesting. It’s a credit-card-sized device that holds other credit cards, allowing you to swap from card to card and even store gift cards inside its ultra-thin innards. – The company planned a pre-order campaign that would top out at $50,000. They blew past that goal in 40 minutes today, a testament to the desire for folks to leave their plastic at home.”

MA: “With so much energy spent towards turning smartphones into digital wallets, Coin’s idea seems a bit like a throwback, or at least a stopgap solution until those initiatives go mainstream. (Coin’s debut coincided with the U.S. launch of Isis, a mobile wallet initiative backed by AT&T, Verizon and T-Mobile.) Assuming the traditional wallet sticks around for a while, though, Coin might carve its own niche, especially if it can somehow incorporate drivers’ licenses, tickets and library cards, among other stubbornly analog forms of ID.”

ATD: “The company raised a seed round for prototyping from K9 Ventures, Sherpa Ventures, and a handful of angel investors. And today it is launching a crowdfunding campaign on its own site to raise at least $50,000 to start manufacturing, with the goal of shipping next summer. It won’t say how much it raised in seed funding, perhaps because that number would hurt its crowdfunding campaign. The device will retail for $100, with crowdfunding contributors getting it for $50. – In the end, maybe business owners will freak out and refuse to accept the card for some reason. Maybe there aren’t enough people who have the big-wallet problem that I do. Or maybe this is indeed the future of in-store payments. – Whatever the case, I’d start using it tomorrow if I could.”

GO: “Though Coin has seed funding, as a hardware company it still needs to raise funds for manufacturing, Parashar said. It’s launching the product with crowdfunding, hoping to raise $50,000, though it’s not taking to Kickstarter or Indiegogo. Instead it’s taking pre-orders for the device on its website. The first backers will get the device for $50, though it will retail for $100, Parashar said. He expects the first shipments will go to buyers next summer. – I’ll give Parashar credit. Coin’s a novel concept. Unlike other mobile payments companies Coin’s not trying to replace the leather wallet with a digital one. But it’s trying to make that physical wallet a lot less bulky.”

VB: “Coin reminds me of the Card 2.0 from Dynamics, a company which offers similar technology for holding multiple cards in a single card. But while Dynamics has gone on to form partnerships with big payments companies, Coin is directly targeting consumers. – Coin is based in San Francisco and has raised funds from Y Combinator and K9 Ventures. The company plans to announce a new funding round soon.”

TNW: “In short, this is a card to replace all of your cards. Until mobile payment apps are truly commonplace across the world, Coin seems like the best alternative. It’s similar to the Wallaby Card, although Coin gives you greater control over which credit, debit, or gift card you’re using at any given moment. If it means we can finally leave our wallet or purse at home, we’re certainly interested.“
